What is meant by nekuvah?1 There are eleven organs that if there is a perforation of the slightest size that reaches their inner cavity, [the animal] is trefe. They are:2 the entrance to the gullet,3 the membrane of the brain in the skull, the heart and its large arteries, the gall-bladder, the arteries leading to the liver, the maw,4 the stomach, the abdomen, the gut, the intestines, and the lung and the bronchia.

We have already mentioned the definition of the entrance to the gullet.5 It refers to a portion of the esophagus above the gullet which is not fit for ritual slaughter. If there is a perforation of the slightest size that reaches its inner cavity, [the animal] is trefe.

ב

תַּרְבַּץ הַוֵּשֶׁט כְּבָר בֵּאַרְנוּ שִׁעוּרוֹ וְשֶׁהוּא הַמָּקוֹם מִן הַוֵּשֶׁט שֶׁאֵינוֹ רָאוּי לִשְׁחִיטָה לְמַעְלָה מִן הַוֵּשֶׁט. אִם נִקַּב לַחֲלָלוֹ בְּמַה שֶּׁהוּא טְרֵפָה:

3

The brain in the skull has two membranes. If the outer one near the skull bone alone is perforated, [the animal] is permitted.6 If the lower one near the brain is perforated, it is trefe.7 With regard to the portion where the brain extends to the spinal cord, i.e., the portion below the glands where the neck begins, the laws governing [the perforation of] its membranes change.8 If they are perforated beyond the glands, [the animal] is permitted.

ג

4

When the brain itself is perforated9 or crushed, [the animal] is acceptable if its membrane is intact.10 If, however, [it has degenerated to the extent that] it can be poured like water or melts like wax, [the animal] is trefe.11

5

When there is a perforation of the heart to its inner cavity - whether to the larger cavity on the left or the smaller cavity to the right - [the animal] is trefe. If, however, the flesh of the heart is perforated, but the perforation does not reach the inner cavity, [the animal] is permitted.12 The arteries leading from the heart to the lung is considered as the heart itself. If there is a perforation of the slightest size that reaches its inner cavity, [the animal] is trefe.

ה

6

When the gall-bladder is perforated and the liver seals it, [the animal] is permitted.13 If, however, the perforation is not sealed, it is trefe even if the perforation is located close to the liver.

ו

מָרָה שֶׁנִּקְּבָה וְכָבֵד סוֹתְמָהּ מֻתֶּרֶת. וְאִם לֹא נִסְתַּם הַנֶּקֶב אַף עַל פִּי שֶׁהוּא סָמוּךְ לַכָּבֵד טְרֵפָה:

7

[The following rules apply when] a kernel14 is found in the gall-bladder. If it was shaped like a date seed, i.e., its head is not pointed, [the animal] is permitted.15If, however, its head is pointed like an olive seed, it is forbidden, for we can assume that it perforated [the gall bladder] when it entered. [The reason that] the perforation cannot be seen is that a scab developed over the opening of the wound.16

8

When there is a perforation of the slightest size in one of the arteries of the liver where the blood develops, [the animal] is trefe.17 Accordingly, [the following rules apply] if a needle is found in the lobes of the liver. If it was a large needle and its pointed edge was facing inward, it can be assumed that it perforated [the liver] when it entered. If its rounded edge was facing inward, we say that it entered through the blood vessels and [the animal] is permitted.18

9

If it was a small needle, [the animal] is trefe, because both of its heads are sharp and it certainly perforated [the liver].19 If it is found in the large blood vessel, the wide artery through which food enters the liver,20 it is permitted.21 If the flesh of the liver became wormridden, [the animal] is permitted.22

10

When the maw is perforated and kosher fat23 seals [the perforation], [the animal] is permitted. Similarly, whenever a perforation is sealed by flesh or fat that is permitted to be eaten, [the animal] is permitted. The [only] exceptions are the fat of the heart,24 the membrane that is above the entire heart, the diaphragm in the midst of the belly that separates between the digestive organs and the respiratory organs, i.e., the one that when it is cut open, the lungs could be seen and which is called the membrane [above] the liver, the white place in the center [of the liver], and the fat of the colon. In these organs, we do not say that they shield [the perforation] because they are firm.25 A perforation that is sealed with one of these is not considered as sealed.

A portion of fat from a beast that corresponds to a portion of forbidden fat in a domesticated animal does not seal [a perforation] even though it is permitted to be eaten.26

11

When the stomach is perforated, [the animal] is trefe. There is nothing that can seal it for the fat upon it is forbidden.27 Similarly, when there is a perforation of the abdomen or gut that extends to its outer periphery, [the animal] is trefe. If one of them was perforated and the perforation leads to the cavity of the other,28 [the animal] is permitted.29

12

[The following rules apply when] a needle is found in the folds of the gut: If it was from one side,30 [the animal] is permitted.31 If it caused a complete perforation extending [from the outer side] to the cavity of the gut and a drop of blood was found at the place of the perforation, [the animal] is trefe. For we are certain that the perforation occurred before the slaughter. If there is no blood at the place of the perforation,32 [the animal] is permitted. For we are certain that after the slaughter, under pressure the needle caused the perforation.33

13

When an animal swallowed a substance that will perforate the intestines, e.g., the root of the asafetida34 plant or the like, it is trefe, for we can be certain that it perforated them. If there is a question whether or not a perforation was made,35 [the animal] must be inspected.36

When one of the organs of the digestive system through which the food waste passes, i.e., the intestines, are perforated, [the animal] is trefe. Among them are those which are curved and surrounded by each other like a snake that is coiled, they are referred to as the small intestines. If one of them was perforated [on the side where] another [is located], the animal is permitted, for the other [intestine] will shield [the perforation].

14

When the digestive organs were perforated and viscous body fluids seal them, [the animal] is trefe for this seal will not endure.37

When a wolf, a dog, or the like, snatched [an animal's] intestines38 and they were perforated after they were abandoned, we surmise that [the predator caused the perforation and the slaughtered animal] is permitted. We do not say that perhaps [the predator] made a perforation in a place where one already existed.39

If [an intestine] was discovered to be perforated40 and it was not known whether it was perforated before [the animal's] slaughter41 or afterwards, we perforate it again and compare the two. If the first perforation resembles this one, [the animal] is kosher.42 If there was a difference between them, [we presume that the first] occurred before the slaughter and [the animal] is trefe. If the perforation in doubt was handled, the perforation to which it is being compared must also be handled before the comparison is made.

15

When [an animal's] digestive organs protrude outside [its body] without having been perforated,43 [the animal] is permitted. If they were turned upside down,44 [the animal] is trefe even if they were not perforated. [The rationale is that] once [the digestive organs] have been turned upside down,45they will never return to their ordinary functioning and [the animal] will not live.

16

The final digestive organ that is straight and not curved from which feces are excreted in the genital area and is joined [to the body] between the thighs is called the colon. If it is perforated even slightly, [the animal] is trefe,46 as applies with regard to the other digestive organs.

When does the above apply? When the perforation faced the cavity of the belly. When, however, it was perforated at the point where it is joined between the thighs, [the animal] is permitted.47 [Indeed,] even if the entire place where it is joined between the thighs is removed, [the animal] is permitted, provided a length of at least four fingerbreadths48 remains in an ox.49

A fowl does not have a stomach, an abdomen, or a gut. Instead of them, it has a crop and a craw.50

All the factors that render an animal trefe apply equally to a domesticated animal, a wild beast, and a fowl.51

When the roof of the crop receives even the slightest perforation, [the animal] is trefe. What is meant by the roof of the crop? That which becomes extended with the gullet when the fowl extends its neck.52 If, however, the remainder of the crop becomes perforated, [the fowl] is permitted.

18

The craw has two [membranes] covering it. The outer one is red like meat; the inner one is white like skin. If one was perforated and not the other, [the fowl] is permitted unless they are both perforated, even slightly. If they are both perforated, but in places that do not correspond, [the fowl] is permitted.53

The spleen is not one of the limbs which is disqualified because of a perforation of even the slightest size. Therefore our Sages did not include it in that category. Instead, a perforation that disqualifies it has a measure which is not uniform throughout it.

What is implied? One of the ends of the spleen is thick and the other thin, like the shape of the tongue. If the thick end was perforated by a hole that extends from side to side, [the animal] is trefe. If the hole does not extend from side to side, [more lenient rules apply]: If a portion the thickness of a golden dinar remains,54 [the animal] is permitted. If less than that remains, [the perforation] is considered as if it extends from side to side and [the animal] is trefe. If the thin side is perforated, [the animal] is acceptable.55

[The following principle applies with regard to] all of the organs concerning which our Sages said that even the slightest perforation [causes the animal to be considered] trefe. If [that organ] was removed entirely, [the animal] is trefe.56 This applies whether it was eliminated through sickness, removed by hand, or [the animal] was created lacking the organ.

The same laws also apply if it was created with two of that organ, for any extra limb or organ is considered as if it was lacking.57

What is implied? If one of an animal's or fowl's digestive organs, its gall-bladder,58 or the like was removed, it is trefe. Similarly if it was discovered to have two gall-bladders or two of a [particular digestive] organ, it is trefe. Similar laws apply in all analogous situations. If, however, the spleen was removed or two spleens were found, [the animal] is permitted, for [that organ] is not among those listed [by our Sages in this category].

[The statement that] an extra digestive organ causes an animal to be considered trefe applies only when there is an entire extra organ from its beginning to its end and thus two digestive organs are found next to each other as is [sometimes found in] the digestive organs of a fowl59 or the extra organ projects outward like a branch from a bough and it is a separate entity.60 [The latter applies] whether in a fowl or in an animal. If, however, the extra organ returns and becomes combined with the main organ and they are fused at the two ends61 even though they are separate in the middle, [the animal] is permitted and the organ is not considered as extra.
